General Relativity

General
Relativity- A theory invented by Albert Einstein which describes
gravitational forces in terms of the curvature in space caused by the
presence of mass. The fundamental principle of general relativity
asserts that accelerated reference frames and reference frames in
gravitation fields are equivalent. General relativity states that clocks
run slower in strong gravitational fields (or highly accelerated
frames), predicting a gravitational
redshift. It also predicts the existence of gravitational
lensing, gravitational
waves, gravitomagnetism,
the Lense-Thirring
effect, and relativistic precession of orbiting bodies. |
